Bottom line is that the average user, even in their pocket, it will hold up. If you are in the military or construction etc. get a solid case. I mean there could be a bad batch of phones that are weaker. I will put a case on my 6 plus but I like cases and i also take my phone out of my pocket before sitting. With 10 million phones I am sure another issue will arise also before long. Im sure the note 4 when out will have some issues also!
